Title: Fluid pressure motor construction
IPC: B60T13/24
Filed: 1959-10-29
Abstract: 873,034. Fluid-pressure brakes. BENDIX CORPORATION. Oct. 29, 1959 [Dec. 11, 1958], No. 36798/59. Class 103 (1). A fluid-pressure motor C includes a pair of movable walls B1, B2 spaced on opposite sides of a stationary annular partition member 68, 70 in a housing 34, each wall being connected to the partition member by an annular flexible diaphragm 56 or 58 having a radially inner portion connected to the respective wall and an outer premoulded generally axially extending portion 60, 62 wedged between the partition member and the sidewalls of the housing to form a seal therebetween. A boss 48 on wall or piston B2 sealingly slides in a bore in the partition 68, 70 and a boss 44 of wall or piston B1 slides in boss 48, fillets 50, 46 on bosses 48, 44 respectively enable a flow of fluid between the bosses which are prevented from separating by a ring 54. A plate 80, clamping diaphragm 56 to wall or piston B1, houses a valve member 108 movable by a pedal F and rod 110. In operation, valve member 108 is moved to engage seat 122 with diaphragm 120 which is then moved from seat 118 to connect vacuum chamber 116 to chambers 92 and 96 via passage 126 and the gap between bosses 44, 48. Since chambers 94, 98 are open to atmosphere, the pistons B1, B2 move to operate the master cylinder piston 10 to force fluid past check valve 26 to the brake cylinders. Piston 10 is moved by pistons B1, B2 through a rubber pad 142 which deforms to engage valve member 108 and transmit " feel " to the pedal F. The pistons eventually reach a lap position where diaphragm 120 engages seats 122 and 118. Release of pedal F, allows a spring 130 to return member 108 to the release position where chambers 92, 96 are vented to atmosphere via passages 126, 114 and chamber 98. Should the power unit fail, then pedal F operates piston 10 through members 108, 142, 136 and rod D, a washer 132 on member 108 preventing the block 136 being pushed out of boss 44. The position of piston 10 and seal 20 is adjusted by screwing a cup 148 into, or out of, a boss 150 of a closure plate 82 held in shell 34 by a spring ring 84, the cup forming an abutment for the plate 80 and pistons B1, B2 in the release position. When seal 20 just uncovers port 24 as seen through reservoir plug 164, a lug 162 of a spring ring 160 is inserted in complementary holes in boss 150 and cup 148 to lock the cup in the adjusted position, thus ensuring closure of port 24 on initial movement of piston 10.

Filed: 1928-12-13
Abstract: 326,260. Electrolux, Ltd., (Platen- Munters Refrigerating System Aktiebolag). Dec. 13, 1928. Refrigerating, absorption machines for. - In continuous-cycle systems containing inert gas in the evaporator 10 and absorber 11, heat exchangers are provided between different parts of the gas system so that counterflow of the media in a vertical evaporator may be effected without the aid of heat or mechanical circulating means. The conduit 13 leading the relatively pure inert gas, e.g. hydrogen, from the absorber first extends above the evaporator level, to provide a static head of gas tending to prevent flow of gas towards the top of the absorber, and then extends downwardly at 15 where it is cooled by upwardly flowing mixture of nert gas and refrigerant in a pipe 18 leading from the evaporator. At starting, the static head of inert gas causes the gas mixture to flow out of the top of the evaporator by pipe 16, and the mixture may first cool liquefied refrigerant flowing through a pipe 9 from the condenser 7, 8 to the top of the evaporator. After flowing upwardly through pipe 18 the gas mixture flows downwardly througn a pipe 19, which may be arranged to exchange heat with the inert gas pipe 13 so as to cool the upflowing inert gas, and then enters the bottom of the absorber. Surplus liquid from the evaporator may be led through a pipe 20 and seal 21 either to the liquid space of the absorber, or through a coil passing around the absorber to cool it by evaporation, and a drain pipe 22 may extend from the inert gas pipe 15 to the liquid seal 21. The apparatus includes a rectifier 4 cooled by liquid refrigerant, liquor heat exchanger 24 and thermal pump 3 of known forms.

Abstract: 806,028. Automatic - exchange systems; magnetic amplifiers. COMPAGNIE INDUSTRIELLE DES TELEPHONES. Dec. 10, 1956 [Dec. 8, 1955], No. 37710/56. Classes 40 (4) and 40 (9). In a system for selecting one out of a number of calling lines, or one out of a number of routes to be taken by a telephone call through an exchange, each line or route is associated with a magneto-static relay, the energization of any one of these operating a pilot relay which locks out all the other relays. The magneto-static relays are provided with three control windings and a biassing winding the control ampereturns (NIc)/out (Is) characteristic being as shown in Fig. 7. The relays R1 . . . Rn are arranged as shown in Fig. 4. Available routes or calling lines are marked by energizing corresponding windings R11 ... Rn1 of the relays. Thus, supposing both R21 and R31 are energized-then relay R2, in operating, energizes the pilot relay B which in turn applies opposing current to all windings R12 . . . Rn2 of the relays to prevent any other relay except R2 operating. Furthermore, relay R2 energizes opposing windings R33 ... Rn3 in all succeeding relays to establish priority for R2. In Fig. 7, P1 represents the condition of the first choice relay R2 when the control current is applied to winding R21. Subsequent application by the pilot relay of the current to winding R22 brings the point back to P2, the relay still remaining operated. Any relay whose winding R11, say, is operated after the application of current to winding R12 will be represented by P3 and remain unoperated. Point P4 represents the state of a relay, say R3, succeeding R2 in which the current in winding R31 is opposed by current in both of windings R32, R33.

Filed: 1962-10-05
Abstract: 980,210. Protective arrangements for cathoderay tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct. 5, 1962 [Oct. 9,. 1961], No. 37801/62. Heading H1D. [Also in Division H4] To prevent burning of the screen of a cathoderay tube by the electron beam when the tube is switched off, the first anode is comprised of two mutually-insulated parts 6a, 6b connected respectively to a circuit including a capacitor 27 and voltage divider 28, 29, and to a circuit including a potentiometer 32 and resistors 30, 31, the discharge time-constant of the latter circuit being less than that of the former. Thus when the tube is switched off the voltage of part 6b decreases more rapidly than that of part 6a to cause deflection of the electron beam in the direction II, where it impinges on the part 7 of the second anode to discharge this part, the part 8 and a conductive coating 11 connected to the screen, before the deflection due to the voltage difference between parts 6a, 6b has decreased to zero. Adjustment of potentiometer 32 to make the voltage of part 6b equal to that of part 6a produces a beam direction I during tube operation, the positive voltage for the parts 6a, 6b being supplied from the horizontal deflection circuit through its efficiency diode circuit and a potentiometer, Fig. 1 (not shown). Fig. 3 shows a simplified arrangement in which upon switching off, the voltage of anode part 6d decreases more rapidly than that of part 6 c  so that, since part 6d has a small aperture, the electron beam is suppressed completely (although in this case parts 7, 8, 11 are not discharged). During tube operation the voltage of parts 6c, 6d will always become equal. The circuit arrangements and tube constructions shown in Figs. 2 and 3 may be interchanged. The supply and control circuits for the tube are described, Fig. 1 (not shown), and typical values are given for their resistors and capacitors and for those shown in Figs. 2 and 3.
